Everything works fine for few hours and then user gets logged out automatically. I have been unable to find an exact way how to reproduce it, but I see this quite frequently.

I've also noticed that cookie values changes on each request. Probably this is the way Laravel session is supposed to work.

My session.php config file

'driver' => 'memcached',
'lifetime' => 10000,/*around 1 week*/
'expire_on_close' => false,
'files' => storage_path().'/sessions',/*not being used*/
'connection' => null,
'table' => 'sessions',
'lottery' => array(2, 100),
'cookie' => 'example_session',
'path' => '/',
'domain' => '.example.com',
'secure' => false,
